Serial No. 498,808.

My invention relates to machines for applying adhesive and for fastening wraprs of packages and is particularly adapted or fastening by means of paste or other adhesive the folded wrappers of bread and the like.

An object of my invention is to provide means for ap lying-paste, or other adhesive material to t e wrappers of packages and 10 a further object of my invention is to provide means for fastening or sealing packages. I accomplish these and other Ob]GCtS by m invention a referred embodiment of whic is illustra in the accompanying drawing, 16 in which Figure 1 is a plan view of the machine and Figure 2 is a side view with the paste container shown in section on the line 2-2 in Fi re 1. I so imilar characters of reference refer to similar parts throughout the several views.

My im roved machine is particularly adapted or fastenin the ends of the wrappers on loaves 0 bread and the pre- 25 ferred form of the machine illustrated in the drawing is adapted to be used for that purose. P Referring to the drawing, the machine illustrated com rises an open trough having so a bed 1 and sidb walls 2, 2 upon which are set counterpart paste containers 3.

These paste containers 3 are 0 n and are each provided with a roller 4 reel rotat able with their shafts 5 and are ad ustabl positioned by means of a cam 6 from whic they are suspended by means of an arm 7.

The cams 6 are rotatable by handles 8 kead on the drafts 9.

he side walls 2 are provided with slots 10 which are carried adjacent the bed 1 to a point approximately in the plane of the open end of the paste container 3 from which point they are continued upwardly as shown at 10 at an obtuse angle to the top of the side walls 2.

The rollers 4 which form end closures for the paste containers 3 are spaced from the overhang 11 of the bed 1 a distance sufiicient to permit the ends of the wrappers to M pass thereunder. The bearing shafts 5 of the rollers 4 are preferably carried in elongated bearing sockets 12 to permit free movement longitudinally of the paste receptacles.

A conveyor of any desired type may be provided to carry the wrapped packages.

The machine being thus assembled, the loaves of. bread 14 having wrappers placed thereon in any desired manner are fed to the machine on the bed 1 in the direction of the arrows in Figure 1, with the folded ends 15 of the wrapper lying fiat and projecting through the slots 10 and these folded ends q 15 of the wrapper are passed under the rollers 4 whereby paste from the paste container 3 is applie to the exposed. surface. As the package 14 is moved along the bed 1 the inclined portion 10 of the slot will cause the ends 15 of the package to be folded upwardly and the sidewalls 2, 2 of the trough being spaced apart a distance equivalent to the ength of the completed package, will cause the folded ends 15, so provided with adhesive material, to be pressed a ainstthe package thus completing the sealmg of the package, which is then carried away by the conveyor 13.

Having thus described my invention, what I claim is:

1. In a device of the character described the combination of a trough having a bed and slotted side walls, means mounted on the said side walls exteriorly of the trough for applying adhesive material to the end of a flap of a wrapper projecting through said slotted side wall and comprising a container, a roller forming a loose closure for the container, elongated bearing slots in the walls of said container, a shaft in said bearin slots and rotatably carryin said roller, ans supporting means for sai container comprisin a cam, a shaft eccentrically mounted in sai cam, a support for said shaft, an arm carried by said cam and secured to said container and key means adapted to rotate the said shaft.

2. In a device of the character described, means for applying adhesive material, comrising a container for said material, a roller orming a loose closure for the container, bearing slots in the walls of said container, a 100 shaft in said bearing slots and rotatably carryi g said roller, in combination with supporting means for said container com risin a cam, a shaft eccentrically mounted in aai 5 cam, 11 support for said shaft, and an arm carried by said cam and secured to said container. 7
